Check out mine on my website or the classifieds here.

I've had a jbobo thumper for 3 years, best investment I've made next to my Ulterra.

Thank you sir! I hope and expect it to last for many more years of catching for you!

jbobo, how much do you get for thumper box?

I sent you a pm in in ft worth.

thank you!

There's a time and place for it. It's not needed every time you fish.

Well I ordered a motor and controller and bracket from Amazon..........
Even if it doesn�t help me catch fish at least I will be able to annoy other boats

It�ll be similar to this one: but not remote control

What will really annoy them is when your catching fish and they are not.

I know this first hand...

I may switch to a 90* angle power seat motor..........

Nice job BigPoppa. you will never go back, welcome to the world of the dead stick junkies.

EXACTLY! Pretty soon you'll be wanting it to stay cold a few extra months. It's hard to beat the thump.

BigPoppa, what is the little doohickey connected to the motor shaft?

It�s an aluminum wheel with 4-40 holes to fit 6 mm shaft and I added 3 flat brackets cut on angle. But that motor is only 30 rpm and and not that strong and the set screw wouldn�t hold so the wheel spun on shaft so I booger welded it on. The wheel is aluminum so I couldn�t weld it but I welded the three brackets/arms together and then I welded them to the end of the shaft and they are screwed to the wheel. At first I tried just screwed to the wheel with the 4 40 screws and the set screw holding the wheel on the shaft but the set screw did not hold and the shaft would spin inside the wheel.
If I had drilled a hole in the shaft for the set screw to go into it may have held. And cut the lift arms out on a single plate that could bolt to wheel side as whole- a circular plate with 3 angled arms coming off - kind of like a 3 tooth saw blade.......if Probally would not need any welding.

If I was to build another one I would get a 90� power seat motor, 190 rpm (with the controller deal to slow it down) that has a larger shaft and would weld a piece to it to raise the hammer.

If the little motor I have on it now wears out I will switch to the power seat motor and make it a double lift bracket/ lift arm - diamond shaped
